My alter ego is a character I call Superhero PhD or Dr. PhD. It started as a last-minute solution to a costume for a superhero-themed 5K. Then it was just a fun gag to write about my everyday work experiences as a scientist. Writing about yourself in the third person in the dramatic style of a comic book hero makes the tedium of my work seem more fun.
